Immunoenzyme technology has been widely used in immunology, microbiology, parasitology and so on. Due to its advantages of high sensitivity, stable reagents, simple equipment, and safe operation, it has also been applied to the food field in recent years to detect physiologically active substances in certain foods.
basic concept
1. Immunity: In general, immunization is the defense of human and animal bodies, the elimination of foreign substances (foreign matter) into the human body, and the identification and removal of dead, degenerative substances and calm mutant cells of insurgents in the body to protect and stabilize their own Protection mechanism.
2. Antigens: Antigens are those substances that can induce the body's immune system to produce an immune response, produce antibodies and sensitize effector lymphocytes, and specifically bind to them in the body and outside to produce an immune response.
3. Antibody: It is a protein molecule that can specifically bind to the corresponding antigen. Like other biological macromolecules in the body, it is a product of cells, secreted into body fluids or expressed on the surface of cells. 4. Antigen and antibody reaction: The reaction of antigen and antibody in vitro is also called serological reaction. Such reactions can be detected by immunological methods.
